Title: Method for adjusting resistance value of fur brush
Inventor: SHIMIZU SHIGERU
IPC: A46D1/00
Filed: 1985-07-18
Abstract: PURPOSE:To efficiently remove residual toner and to smoothly recover the toner without clogging a fur brush by impressing a voltage more than the prescribed value to the fur brush during the prescribed period. CONSTITUTION:After an impression bias voltage raised to 1,000V is impressed for 40sec, it is returned to its original 400V. As a result many leakage currents, which can be found upon impression of an initial voltage of 400V, disappear to obtain an extremely stable constant current. This occurs because the rayon thread of a partially low resistance part is selectively burnt out by raising the bias voltage. An average rotating resistance value available from a current value whose leakage current is removed is about 29MOMEGA at a high level when the initial voltage is impressed. After the high voltage is impressed and processed,the leakage current disappears and simultaneously its magnitude is increased compared with that at the early stage, whereby the average rotating resistance value corresponding to the increase drops to 10MOMEGA. And the resistance value provisionally dropped is not returned to its original and holds stably almost the same value.

Title: Programmable controller
Inventor: YAMAUCHI TAKASHI
IPC: G05B19/048
Filed: 1988-06-27
Abstract: PURPOSE:To use a programmable controller suitably for an EPROM and EEPROM even when no setting pin is used by switching the operating voltage and high-impedance state between the writing and reading cycles. CONSTITUTION:A processor 1 investigates an operation whether it is data reading or not and, when the operation is data reading, sets the 1st pin 2a to a high-impedance state by setting an output port 1a to a high level and turning off a transistor Q. In this case, the content of the EPROM is held and to trouble occurs even when writing operations are performed while an EPROM is inserted into a socket. When an EEPROM is set, data writing can be performed normally. When writing operations are performed, on the other hand, a 5V power supply is connected to the pin 2a by setting the port 1a to a low level and turning on the transistor Q. In this case, data reading can be performed normally even when either the EPROM or EEPROM is inserted into the socket. Therefore, no setting is required and damage of the ROMs by wrong setting can be prevented.

Title: Device for controlling hydraulic driving tool
Inventor: SHIMADA KEISUKE
IPC: B30B15/16
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To lengthen the service life of a valve change-over mechanism without restart and malfunction even if a starting switch is continuously pressed or a lower limit switch develops chattering. SOLUTION: At the time of pushing the start switch SW3, an one shot multi- circuit 15 is driven and one pulse is outputted. This pulse is transferred to a self-holding circuit 16 and the self-holding circuit 16 is self-held and an H level signal is outputted till resetting a signal. In this result, a transistor 17 is turned on and a relay R1 for lowering a ram is worked. When the ram reaches the lower limit position, the lower limit LS4 is opened and a self-holding circuit 21 self-holds the signal at H level with a signal from a one shot multi- circuit 18. This signal is delayed with a delay circuit 22 to turn on a transistor 23. In this result, a relay R1 for raising the ram is worked.

Title: Surface treated steel sheet and roll formed section easy to drive screw
Inventor: MATSUMOTO MASAMITSU
IPC: C23C2/06
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To obtain a steel sheet easy to drive screws in for joining plated steel sheets with self-drilling screws by specifying surface roughness of the side of the sheet into which screws are likely to be driven. SOLUTION: At the time of bonding the plated steel sheet by using self- drilling screws, the surface roughness of the side into which screws are supposed to be driven is controlled to 1.2 to 10 μm, preferably to 2 to 7 μm by the arithmetical mean roughness Ra. As the plating kinds of the plated steel sheet, in the viewpoints of corrosion resistance, workability or the facilitation of maintenance, galvanizing, galvannealing (zinc-5% aluminum alloy plating, Zn-9% Fe alloy plating or the like), aluminum plating and aluminum alloy plating (55% aluminum-zinc alloy plating or the like) are preferable. In this way, in the case the pointed tip of a screw is pressed against the surface of a plating film, the pointed tip of the screw is held to the part, the side slip of the tip is suppressed, and screwing can easily be executed.

Abstract: PURPOSE:To make a screw rod hardly deflected longitudinally and to the right or left against the center axis by forming coupling sections having an angular cross section, upper spigot sections, and lower spigot sections on a plug section and a socket section so that they are coupled with each other. CONSTITUTION:In this joint section structure, the male lower spigot section 54b of a plug section 54' is coupled with the female upper spigot section 55b of a socket section 55', and the male upper spigot section 54f of the plug section 54' is coupled with the female lower spigot section 55f of the socket section 55'.

Abstract: PURPOSE:To aim at improvement in axial restoring force, by arranging a conical magnetic pole plate so as to maximize a facing area at the minimum gap between the facing surfaces, in case of a thrust type magnetic bearing using repulsion between homopolar magnetic poles. CONSTITUTION:A downside magnetic bearing 2 and an upside magnetic bearing 3' are set up so as to cause the whole gap area to be opposed when the magnetic bearing 3' exists at an upward limiting point of a shaft 1 or when gap delta is the minimum, balancing with a gap delta deg. being far larger than that, and thereby resultant force (BD+FG-A) is reduced to zero. In addition, a downward limiting point of the shaft 1 is set up for the maximum gap. With this constitution, when the gap delta0 moves to delta1 by dint of an upward vibratory force FU opposing areas of gap increases, the increase rate of downward component force  BD increases, and a downward restoring force BC become increased whereby restored. In case of a reverse vibratory force FD, it is the same as the above case. In this way, improvement in restoring force is attainable.

Abstract: PURPOSE:To decide the measuring period automatically in response to acceleration, deceleration and inertial running of a vehicle and to record data correspondingly by an apparatus which includes means for giving two types of long and short measuring periods and measuring means adapted to perform measurement in accordance with operation command information. CONSTITUTION:When powered on, a clock generator 14 in a measuring apparatus body 5 is operated and the measuring program set in an arithmetic control section 12 is executed for each clock. With a start button 6 being pressed, the measured data in a memory section 11 is cleared and an input section 10 takes in voltage from DCPT1, current from DCCT2, running pulses from a tachometer generator 3 and an operation command from an operation command section 4 at the period set by a digital switch 9 to temporarily store them in the memory section 11. A running time, running distance and power consumption are determined based on the stored content in the control section 12. The results are sequentially output to an output section 13 to be recorded at 15. With this, measurement is repeated at the period set by the switch 9, and measurement is made at the period set by a switch 8 upon receiving the brake command and at the period set by the switch 9 when entering inertial running.
